Does 7,5 make the equation y=x+2 true

No

Step-by-step explanation:

(7,5) are coordinates. which means one point is x and the other one is y.

So, 7=x and 5=y.

Substitute those in:

5=7+2

Simplify:

5=9

Which isn't true. So the answer is no.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
